Pull gfs2 revert from Andreas Gruenbacher:
"Revert bad commit "gfs2: Fix use of bio_chain"
I was originally assuming that there must be a bug in gfs2
because gfs2 chains bios in the opposite direction of what
bio_chain_and_submit() expects.
It turns out that the bio chains are set up in "reverse direction"
intentionally so that the first bio's bi_end_io callback is invoked
rather than the last bio's callback.
We want the first bio's callback invoked for the following reason: The
initial bio starts page aligned and covers one or more pages. When it
terminates at a non-page-aligned offset, subsequent bios are added to
handle the remaining portion of the final page.
Upon completion of the bio chain, all affected pages need to be be
marked as read, and only the first bio references all of these pages"
